Emergent Origin of the Born Rule from Pre-Locking Structural Robustness in Continuous Quantum Measurement

This work presents an operational and falsifiable mechanism by which Born statistics emerge dynamically from continuous quantum measurement, without assuming wavefunction collapse or probabilistic postulates. Instead of treating the Born rule as a fundamental axiom, outcome probabilities are shown to arise from the pre-locking dynamical structure of measurement trajectories. Using stochastic quantum trajectory simulations of continuously monitored qubit systems, the study introduces the concept of a locking time, defined as the moment at which measurement dynamics irreversibly stabilizes into a definite outcome. Crucially, this locking transition is preceded by a finite pre-locking regime in which multiple outcome configurations coexist and compete dynamically. To quantify this competition, a structural robustness functional is defined as the time-integrated stability of each outcome configuration prior to locking. Normalized robustness values provide a dynamical prediction for final measurement outcomes using only pre-locking information. These predictions exhibit statistically significant correlation with observed outcomes before locking occurs, while the same construction applied after locking shows no predictive power, providing a falsifiable internal control. The mechanism is demonstrated to be robust across wide ranges of measurement strength and decoherence parameters and is shown to be independent of the measurement basis, reproducing the same behavior for measurements performed in both σz and σx bases. No fine tuning or hidden-variable assumptions are required. These results support a reinterpretation of the Born rule as an emergent statistical consequence of measurement dynamics, rather than a fundamental principle. Probabilities arise from accumulated dynamical stability during the measurement process itself, shifting the role of probability in quantum mechanics from an axiom to an operational outcome of pre-locking structural competition.
